Researchers based in China have been exploring the benefits of using freestanding (FS) gallium nitride (GaN) as a substrate for micro light-emitting diodes (LEDs) [Guobin Wang et al, Optics Express, v32, p31463, 2024]. In particular, the team developed an optimized indium gallium nitride (InGaN) multiple quantum well (MQW) structure with improved performance at lower current injection (~10A/cm2) and lower driving voltages as suitable for the advanced micro-displays used in augmented (AR) and virtual reality (VR) setups where the higher cost of FS-GaN can be compe...

Samsung Display is one of the biggest innovators in the industry. Among the wildest concepts the division has worked on over the years is the extendable display. And on top of that, there's another one that uses 50% less battery power. So the revolution is about to fall.  There is a conference this week IMID 2024 and Samsung here she performed its latest generation of stretchable display, which has continued to evolve and improve since we were first able to see it (which was back in 2017). It is based on micro LED technology and can be extended by 25%. In other wor...

It was reported earlier this year that Apple cancelled plans for a micro-LED Apple Watch, finding them too difficult to produce in the quantities that would be needed. Display supplier LG was set to make a key component for this display, and is now said to be seeking compensation for the cancellation of the project … Apple’s move toward micro-LED Apple is so still to complete its transition to its third display technology, OLED: Originally, it used LCD with conventional backlighting Then it moved on to LCD with mini-LED backlighti...

In June 2022, Tianma Microelectronics announced plans to establish a 1.1 billion Yuan ($164 million USD) full-process microLED pilot line, in Xiamen. A few days ago, Tianma announced that its production line has commenced trial production. The new production line is co-located with a 8.6-Gen LCD fan at the Tongxiang High-Tech New Town in Xiamen. Tianma also detailed the first microLED display is produced at the new plant, a 7.5" module aimed towards tiled displays, that offers a brightness of 600 nits and a low 5% reflectance. This is the first time ...

Researchers based in Korea report on size-dependent characteristics of indium gallium nitride (InGaN) red micro-scale light-emitting diodes (micro-LEDs) fabricated on 4-inch silicon (Si) substrates [Juhyuk Park et al, Optics Express, v32, p24242, 2024]. The team from Korea Advanced Institute of Science and Technology (KAIST), Korea Advanced Nano Fab Center (KANC), and Chungbuk National University, sees its work as being pioneering, adding: “This work is the first investigation into the size-dependent characteristics of InGaN/GaN red micro-L...

Los Angeles-based Q-Pixel has developed microLED display technology which it says has achieved the highest resolution, active-matrix colour display in the world. Q-Pixel’s display offers 6800 pixels per inch (PPI), surpassing current displays. The technology replaces the traditional three subpixel LEDs with a single polychromatic LED. Q-Pixel has fabricated its display entirely using microLED pixels, technology which has been notoriously challenging to implement. Unlike most advanced VR displays, which use micro-organic LEDs (micro-OLEDs), Q-...

Jun. 3, 2024 ---- Efforts to reduce the cost of Micro LED chips through size miniaturization are ongoing. Companies like LGE, BOE, and Vistar continue to invest in large display applications, while AUO has been focusing on developing smartwatch products. There is also growing demand for new display applications in head-mounted devices and for automotive uses. TrendForce’s “2024 Micro LED Market Trend and Cost Analysis Report” reveals that the market value of Micro LED chips is projected to reach $580 million by 2028, with a CAGR of 84% f...

The Micro LED development was hit hard in March 2024 after Apple decided to cancel the Micro LED watch project. Slowdowns in aspects including investments, technological development, and widespread use are unavoidable. Nevertheless, chip miniaturization, which is closely associated with cost reduction for Micro LED chips, continues to move forward. LGE, BOE, Vistar, and other manufacturers have invested in large-sized display applications, while AUO continues developing its watch products. Regarding novel display applications, Micro LED can be seen in head-...
